Hi Product Hunt! I'm the maker of Mojito. Personal AI is here, but most personal agents (cloud ones like Meta's Muse included) sit next to a fixed app. They can chat and run tasks, but the app itself only changes when the vendor ships an update. So over a weekend I tried the opposite with Claude. I tore out most of my daily planner's code, kept a thin frame (a small hub that stores data and sends pushes), and made Claude Code on my own Mac the backend. When I want something changed, I say it in the app's chat ("put the next step on top, in bold"). The agent edits the code, builds, ships the update to my phone and pushes me a note. Bigger changes wait for my OK. In one day it grew a subscriptions page, an iPhone home-screen web app with push, a fix for duplicate notifications, a desktop redesign and an English UI, all from one-line requests. It's MIT and alpha, and you host it yourself, so it's for tinkerers for now. Your data and logins stay on your own machines. I'd love to hear what you'd ask your own app to change, and where you think this breaks first.
